long_description \
                The BIND DNS Server is used on the vast majority of name \
                serving machines on the Internet, providing a robust \
                and stable architecture on top of which an \
                organization's naming architecture can be built. The \
                resolver library included in the BIND distribution \
                provides the standard APIs for translation between domain names \
                and Internet addresses and is intended to be linked with applications \
                requiring name service. This is the older 9.18 release series, \
                intended to be used on systems where 9.20 doesn't work.

notes "******************************************************
* To setup named to run, you need to copy named.conf.dist
* to named.conf:
* sudo cp ${prefix}/etc/named.conf.dist ${prefix}/etc/named.conf
* and edit as needed. If you use the default zone files for
* 127.0.0, localhost, and the cache, you also need to copy
* those files:
* sudo cp ${prefix}/var/named/db.127.0.0.dist ${prefix}/var/named/db.127.0.0
* sudo cp ${prefix}/var/named/db.cache.dist ${prefix}/var/named/db.cache
* sudo cp ${prefix}/var/named/db.localhost.dist ${prefix}/var/named/db.localhost
* 
* You may want to generate a key (for rndc):
* $ sudo rndc-confgen -a
*
* Remember to secure your configuration:
* http://www.cymru.com/Documents/secure-bind-template.html
*
* The bind9 port now sets up named to run as non-root, you may
* need to adjust your named.conf to put the pidfile and any
* logging into a directory where this new user can write files.
